Question

Импульс тела 30 килограмм метров в секунду какова масса тела если его скорость 54 километра в час

Answer 1

Дано:           С.И      Решение
V=54 км/ч    15 м/c  P=mv
P=30 кг*м/c             m=P/V
m-?                          m=30/15=2 кг
Ответ:m=2 кг

Answer 2

Calculating the Mass of the Body

To calculate the mass of the body when its impulse is 30 kilogram meters per second and its speed is 54 kilometers per hour, we can use the formula:

Impulse = Force × Time Impulse = Mass × Change in Velocity

First, let's convert the speed from kilometers per hour to meters per second: 54 kilometers per hour = 15 meters per second.

Now, we can use the formula to calculate the mass: Impulse = Mass × Change in Velocity 30 kilogram meters per second = Mass × 15 meters per second Mass = 30 kilogram meters per second / 15 meters per second Mass = 2 kilograms.

Therefore, the mass of the body is 2 kilograms.
